As the price of bitcoin transactions fluctuate on MtGox, so do the prices of my shirts at SquareWear. Not that it changes anything, but I wonder what to root for, increase in price of BTC, decrease, or stability.
Increases bring the cost down relative to people's native currency (they'll likely soon be under 2Ƀ), but might make people reluctant to spend. Decreases in price may spur purchases (people wanting to spend while it still has value). Stability may take the concern of relative value out of people's mind and allow them to make normal purchasing decisions.
For other businesses selling in BTC, do you notice sales differences based on the fluctuations in BTC price? For BTC spenders, do you find your own purchases affected by Mt Gox price?
